View Full Version : Film Resolution

What is the proper resolution for film to be rendered at?
03 March 2002, 11:40 PM
somewhere between 3 and 4k DPI.

Hmmmm, so its really not much different than like say print size for something 8.5x11? That's kind of suprising, I always thought it was some Massive size.

print size is 150-300 dpi, 3-4k dpi is massive compared to print resoltions, ff you are talking physical size I am not sure what size film is rendered out as.

2k is save -- Pixar is said to even render their frames at 1.5k.
Back in the old days it was believed that you had to render at 4k for film (I believe T2 was rendered at that res). But it turned out that due to grain etc., real film never gets as sharp as a a resp. 4k render.

Ok, so the resolution should be around 2000 dpi. Then what should the actual size of the render be?

DPI? I think you mix st. up here. DPI are not related to image width or hight. They are a scaling factor for printing, but not for printing on film.
Look at this thread:

that should be the width/height in pixels, not DPI.
you surely dont want to render frames of 2k at 2000 DPI.
I think you will suffer from heart failure if you do that. (at least your computer will, if 2000DPI is even possible..)

Errm, you miss the point here too. A 2k is a 2k is a 2k image. It doesn't matter how many dpi. Dpi's are just a scaling factor that is used after the image has been created and needs to be reproduced on some medium.
Only if you print the image on paper (as opposed to printing on film), dpi's start to matter), but even then they start to matter long after your render has been finished.
Hence, if you render 2k at 2000 dpi, your image will be 2048 pixels wide. If you render 2k at 72 dpi, your image will still be 2048 pixels wide.
The only difference is that if you print the former on paper, it will come out one inch wide while the latter will come 28,44 inches wide.
Using a pixel-based scale and using a dpi-based is mutually exclusive. It doesn't make sense.

Right so mow many pixels high and across does the render need to be for film.

There is no "the resolution". It depends on your frame aspect.
Acadmey e.g. is 4:3; that would mean 1536 pixels vertically at 2k.
But there are a few more formats ...

yeah, thats what i said :D
i was kinda refering to the file size.

The most common format used are 1828x1332, 2048x1556, 4096x3112
But many time you render at lower resolution and the scale up in comp.

Thanks for the straight answer alex.

actually, on my scanner and film recorder the size is 2048X1536 and 4096x3072.
There are other formats but this is the cineon standard.
T2 was rendered at 2K at the very best. Some of the shots were less. Way less. Same with Jurassic Park. It all depends on the shot and how much of the frame your CG element takes up.
Matte World digital does use the full 4K res and so do a few other places but the standard is 2K.

which scanner are you using?
We get our scanning and recording done in Cinesite (UK) and we always get 2048x1556 for 2k or 4096x3112 for 4k
